How to Apply for Senior Data Engineer

at Movement Labs

🏢 About Movement Labs

Movement Labs is a mission-driven organization that builds data infrastructure for progressive social movements and grassroots campaigns, partnering with hundreds of organizations to power voter targeting and experimental research. Working here means your engineering directly supports election cycles and social change at scale, not corporate profit. The fully remote, collaborative culture values cross-functional leadership and mentorship.

About This Role

As a Senior Data Engineer, you'll design and maintain pipelines, APIs, and orchestration layers that serve voter datasets and randomized controlled trial (RCT) platforms for hundreds of partner organizations. Your work will directly optimize cost, runtime, and reliability during high-volume election cycles with millions of concurrent outreach attempts. You'll also lead projects across systems and mentor teammates, making a tangible impact on progressive campaigns.

💡 A Day in the Life

A typical day might involve reviewing code from teammates, debugging a pipeline issue that arose overnight, and optimizing a SQL query that's slowing down voter targeting for a partner organization. You could also attend a cross-functional meeting to plan an RCT deployment, then pair with a junior engineer on API design. During election cycles, you might be on-call, monitoring systems for spikes in outreach attempts and ensuring reliability under pressure.

🎯 Who Movement Labs Is Looking For

  • 3+ years of data engineering experience with production systems, including building and maintaining scalable ETL pipelines and APIs.
  • Strong proficiency in SQL and Python (or equivalent), with a track record of optimizing systems for cost, performance, and reliability under load.
  • Experience with orchestration tools (e.g., Airflow, Dagster) and cloud data warehouses (e.g., BigQuery, Snowflake) in high-volume environments.
  • Comfortable with on-call rotations, including evenings and weekends during election cycles, and passionate about using data for progressive social change.

📝 Tips for Applying to Movement Labs

1

Highlight any experience with voter files, political data, or randomized controlled trials (RCTs) in your resume—Movement Labs specifically values domain knowledge in progressive analytics.

2

Quantify your impact on system reliability, cost savings, or runtime improvements during peak loads (e.g., 'reduced pipeline cost by 30% during election surge').

3

Emphasize cross-functional leadership and mentorship examples, as the role explicitly requires leading projects and mentoring teammates.

4

Mention your willingness and availability for on-call rotations, especially during election cycles, to show you understand the unique demands.

5

Tailor your cover letter to Movement Labs' mission—demonstrate genuine interest in progressive causes and how your engineering skills can support social movements.

✉️ What to Emphasize in Your Cover Letter

In your cover letter, focus on: (1) your experience building scalable data pipelines and APIs for high-volume, mission-critical systems; (2) a specific example of optimizing cost/runtime/reliability during a peak event; (3) your ability to lead cross-functional projects and mentor engineers; and (4) your commitment to progressive social change and why Movement Labs' mission resonates with you.

⚠️ Common Mistakes to Avoid

  • Submitting a generic resume that doesn't highlight data engineering experience with production systems, SQL, and Python—these are hard requirements.
  • Ignoring the on-call requirement or showing reluctance to work evenings/weekends during election cycles, as this is critical to the role.
  • Failing to demonstrate any interest in progressive causes or social movements; Movement Labs seeks mission-aligned candidates, not just technically skilled ones.
